Description
The MS21225-8 is a genuine Textron Aviation nut — a fastening or retaining hardware item used in the airframe. It is applicable to the Citation Longitude and Citation Sovereign or Sovereign+. It carries an export classification of ECCN EAR99.
As an original-equipment (OEM) part supplied directly by Textron Aviation, the MS21225-8 is built to the aircraft maker's specification and cross-references the type design as documented in the maintenance data. Choosing the genuine part over an unapproved substitute preserves configuration control and simplifies inspection sign-offs.
Parts like this are shared across the Cessna Citation aircraft, reflecting how much structure and hardware these models have in common.
Aircraft hardware is called out to a specific specification for each location; an off-the-shelf equivalent is rarely acceptable. The factory part is built to the manufacturer's material and dimensional specification, so it installs as designed without the surprises a generic equivalent can bring.
Sourcing the OEM part protects the airframe's configuration and keeps its service history consistent, which matters for both airworthiness and resale value.
Cessna traces to the company Clyde Cessna founded in Wichita, Kansas in 1927; Textron Inc. acquired it in 1992, and since 2014 it has anchored Textron Aviation alongside Beechcraft and Hawker. Cessna's Citation line, launched with the Model 500 in the early 1970s, grew into the best-selling business-jet family in the world, spanning today from the light M2 to the super-midsize Longitude.
